In reply to nicolat:
The train station place at Cellers was shut up and and ripped out in early january. I doubt it's undergoing a refurb so I guess it's closed for the foreseeable. There's a hotel on the opposite side of the road, prob relatively pricey. Can get appartments in Tremp I think (will prob need some spanish ability to arrange this). Assuming it's not booked up, I'd stay at the eco-refugio in Abella de la Conca. It's a half hour (easy) drive to Terradets but really nice place to stay and friendly vibe, nice owners.
